Lapierre is expected to make his NHL debut on Wednesday.
Lapierre was selected No.22 overall in the 2020 draft and cracked the Capitals lineup out of training camp with Nicklas Backstrom (hip) sidelined. Lapierre had eight goals and 23 assists (31 points) in 21 QMJHL goals last season and picked up five assists in four preseason games. Lapierre will start his NHL career as the Capitals third-line centre, with T.J. Oshie and Conor Sheary on his wings.
